## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power, maneuvering - turn to reverse direction
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing - flare/touchdown
  - terrain condition - water,glassy (contributing factor)
- Nose over, landing - flare/touchdown

## Analysis

THE PLT STATED THAT WHEN REVERSING DIRECTION AFTER AN AERIAL APPLICATION MANEUVER THE ENG QUIT. HE THEN LANDED THE ACFT IN A CREEK DUE TO INSUFFICIENT ALTITUDE TO CLEAR TREES THAT WERE IN THE FLIGHT PATH. UPON TOUCHDOWN THE ACFT NOSED OVER AND CAME TO REST INVERTED. INSPECTION OF THE ACFT REVEALED NO EVIDENCE OF PRE-IMPACT FAILURE OR MALFUNCTION. NO DETERMINATION COULD BE MADE AS TO THE REASON FOR THE ENGINE FAILURE.
